  • ASP.NET MVC Session usage

    - by Ben
    Currently I am using ViewData or TempData for object persistance in my ASP.NET MVC application. However in a few cases where I am storing objects into ViewData through my base controller class, I am hitting the database on every request (when ViewData["whatever"] == null). It would be good to persist these into something with a longer lifespan, namely session. Similarly in an order processing pipeline, I don't want things like Order to be saved to the database on creation. I would rather populate the object in memory and then when the order gets to a certain state, save it. So it would seem that session is the best place for this? Or would you recommend that in the case of order, to retrieve the order from the database on each request, rather than using session? Thoughts, suggestions appreciated. Thanks Ben

  • Server Error in '/' Application (ASP.NET)

    - by baeltazor
    Hi All I just setup up member ship roles and registration on my website with visual web developer using the tutorial on msdn. It works perfectly locally, but when i uploaded it to my server, I get the following page: "Server Error in '/' Application. -------------------------------------------------------------------------------- Configuration Error Description: An error occurred during the processing of a configuration file required to service this request.

  • Extracting Certain XML Elements with PHP SimpleXML

    - by Peter
    I am having some problems parsing this piece of XML using SimpleXML. There is always only one Series element, and a variable number of Episode elements beneath. I want to parse XML so I can store the Series data in one table, and all the Episode data in another table. XML: <Data> <Series> <id>80348</id> <Genre>|Action and Adventure|Comedy|Drama|</Genre> <IMDB_ID>tt0934814</IMDB_ID> <SeriesID>68724</SeriesID> <SeriesName>Chuck</SeriesName> <banner>graphical/80348-g.jpg</banner> </Series> <Episode> <id>935481</id> <Director>Robert Duncan McNeill</Director> <EpisodeName>Chuck Versus the Third Dimension 2D</EpisodeName> <EpisodeNumber>1</EpisodeNumber> <seasonid>27984</seasonid> <seriesid>80348</seriesid> </Episode> <Episode> <id>935483</id> <Director>Robert Duncan McNeill</Director> <EpisodeName>Buy More #15: Employee Health</EpisodeName> <EpisodeNumber>2</EpisodeNumber> <seasonid>27984</seasonid> <seriesid>80348</seriesid> </Episode> </Data> When I attempt to access just the first Series element and child nodes, or iterate through the Episode elements only it does not work. I have also tried to use DOMDocument with SimpleXML, but could not get that to work at all. PHP Code: <?php if(file_exists('en.xml')) { $data = simplexml_load_file('en.xml'); foreach($data as $series) { echo 'id: <br />' . $series->id; echo 'imdb: <br />' . $series->IMDB_ID; } } ?> Output: id:80348 imdb:tt0934814 id:935481 imdb: id:1534641 imdb: Any help would be greatly appreciated.

  • mvc 2.0 updatemodel and my ID Column

    - by femi
    Hello, I have created a create view within my MVC 2.0 Application and by default it included a field for the integer ID Column. This is definitely a field i do not need. If i remove the field and use updatemodel when trying to create the object in code, will something break because it doesnt see my ID column data being passed in, even though it is auto increment? Also, i noticed that in the NerdDinner example, updatemodel was used and after that the repository.save method was called. I thought that updatemodel would save the object to the database..why then call the .save method afterwards? Or have i missed something? Any help with this would be appreciated. Cheers

  • AIR:- Desktop Application related to Window Component (Need some work around)

    - by Mahesh Parate
    Create custom component which contains Combobox and Datagrid. Application conations two button 1) Same Window and 2) New Window. (Label of two button) When you click on “Same Window” button your custom component should get added dynamically in your application. And when you click on “New Window” button your custom component should get open in different window (it should get shifted from application and should appear in Window component). Issue faced:- Clicking on Combobox, list is not getting open as change event doesn’t get fired in Native Window as it looses reference from main application. Issue with DataGrid in Native window (AIR). • DataGridEvent.COLUMN_STRETCH event get affected if try to open datagrid in Native Window. • DataGridEvent get fired but takes long time or even stuck while column stretch Note: Application is an Desktop Application. Only one instance is created in Application for your custom component to preserve current state on your custom component it can be Style, data, or other subcomponent state of your custom component (as above mentioned 2 component are just sample). Please find sample code below:- DataGridStretchIssue.mxml:- < ?xml version="1.0" encoding="utf-8"? < mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:local="*" width="800" height="500" < mx:Script < ![CDATA[ import mx.events.FlexEvent; import mx.core.Window; private var dgComp:DataGridComp = new DataGridComp(); private var win:Window; private function clickHandler(event:Event):void{ dgComp.percentWidth = 100; dgComp.percentHeight = 100; dgComp.x = 50; dgComp.y = 100; if(win){ win.close(); } this.addChild(dgComp); } private function openClickHandler(event:MouseEvent):void{ dgComp.x = 50; dgComp.y = 100; win = new Window();; win.width = 800; win.height = 500; win.addChild(dgComp); dgComp.percentWidth = 100; dgComp.percentHeight = 100; dgComp.x = 50; dgComp.y = 100; win.open(true) } ]]> < /mx:Script < mx:HBox <mx:Button id="btnID" click="clickHandler(event)" label="Same Window"/> <mx:Button id="btnIDOpen" click="openClickHandler(event)" label="New Window"/> < /mx:HBox < /mx:WindowedApplication DataGridComp.mxml < ?xml version="1.0" encoding="utf-8"? < mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%" <mx:Script> <![CDATA[ import mx.events.DataGridEvent; import mx.collections.ArrayCollection; [Bindable] public var cards:ArrayCollection = new ArrayCollection( [ {label:"Visa", data:1}, {label:"MasterCard", data:2}, {label:"American Express", data:3} ]); private function stretchFn(event:DataGridEvent):void{ trace("--- Stretched---") } ]]> </mx:Script> <mx:HBox> <mx:ComboBox dataProvider="{cards}" width="150"/> <mx:DataGrid columnStretch="stretchFn(event)" > <mx:ArrayCollection> <mx:Object> <mx:Artist>Pavement</mx:Artist> <mx:Price>11.99</mx:Price> <mx:Album>Slanted and Enchanted</mx:Album> </mx:Object> <mx:Object> <mx:Artist>Pavement</mx:Artist> <mx:Album>Brighten the Corners</mx:Album> <mx:Price>11.99</mx:Price> </mx:Object> </mx:ArrayCollection> </mx:DataGrid> </mx:HBox> < /mx:Canvas Can any one suggest me some work around to make my code workable... :)

  • How to "enable" HTML5 elements in IE that were inserted by AJAX call?

    - by Gidon
    IE does not work good with unknown elements (ie. HTML5 elements), one cannot style them , or access most of their props. Their are numerous work arounds for this for example: http://remysharp.com/2009/01/07/html5-enabling-script/ The problem is that this works great for static HTML that was available on page load, but when one creates HTML5 elements afterward (for example AJAX call containing them, or simply creating with JS), it will mark these newly added elements them as HTMLUnknownElement as supposed to HTMLGenericElement (in IE debugger). Does anybody know a work around for that, so that newly added elements will be recognized/enabled by IE? Here is a test page: <html><head><title>TIME TEST</title> <!--[if IE]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> </head> <body> <time>some time</time> <hr> <script type="text/javascript"> $("time").text("WORKS GREAT"); $("body").append("<time>NEW ELEMENT</time>"); //simulates AJAX callback insertion $("time").text("UPDATE"); </script> </body> </html> In IE you will see the: UPDATE , and NEW ELEMENT. In any other modern browser you will see UPDATE, and UPDATE Solution Using the answer provided I came up with the following piece of javascript to HTML5 enable a whole bunch of elements returned by my ajax call: (function ($) { jQuery.fn.html5Enable = function () { if ($.browser.msie) { $("abbr, article, aside, audio, canvas, details, figcaption, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, summary, time, video", this).replaceWith(function () { if (this.tagName == undefined) return ""; var el = $(document.createElement(this.tagName)); for (var i = 0; i < this.attributes.length; i++) el.attr(this.attributes[i].nodeName, this.attributes[i].nodeValue); el.html(this.innerHtml); return el; }); } return this; }; })(jQuery); Now this can be called whenever you want to append something: var el = $(AJAX_RESULT_OR_HTML_STRING); el.html5Enable(); $("SOMECONTAINER").append(el); See http://code.google.com/p/html5shiv/issues/detail?id=4 for an explanation about what this plugin doesn't do.

  • Anonymous class implementing interface

    - by Flo
    I have the following code inside a method: var list = new[] { new { Name = "Red", IsSelected = true }, new { Name = "Green", IsSelected = false }, new { Name = "Blue", IsSelected = false }, }; I would like to call a function that requires a list of elements with each element implementing an interface (ISelectable). I know how this is done with normal classes, but in this case I am only trying to fill in some demo data. Is it possible to create an anonymous class implementing an interface? like this: new { Name = "Red", IsSelected = true } : ISelectable

  • Post request with body_stream and parameters

    - by Damien MATHIEU
    Hello, I'm building some kind of proxy. When I call some url in a rack application, I forward that request to an other url. The request I forward is a POST with a file and some parameters. I want to add more parameters. But the file can be quite big. So I send it with Net::HTTP#body_stream instead of Net::HTTP#body. I get my request as a Rack::Request object and I create my Net::HTTP object with that. req = Net::HTTP::Post.new(request.path_info) req.body_stream = request.body req.content_type = request.content_type req.content_length = request.content_length http = Net::HTTP.new(@host, @port) res = http.request(req) I've tried several ways to add the proxy's parameters. But it seems nothing in Net::HTTP allows to add parameters to a body_stream request, only to a body one. Is there a simpler way to proxy a rack request like that ? Or a clean way to add my parameters to my request ?

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • NSFormatter problem: not getting called for the empty string

    - by Enchilada
    I have created a custom formatter for my (read-only) table column. It looks like this: - (NSString *)stringForObjectValue:(id)anObject { NSAssert([anObject isKindOfClass:[NSString class]] && anObject != nil, @"invalid object"); if ([anObject isEqualToString:@""]) return @"EMPTY"; else return [anObject stringByAppendingString:@"++"]; } Very simple. The corresponding objects are just strings, so it's an string-to-string formatter. All non-empty string objects are returned with @"++" appended to them. Empty string objects should be turned into the @"EMPTY" string. The @"++" gets appended to non-empty strings just fine. The problem is, @"EMPTY" never gets shown! My formatter is never called by Cocoa when the underlying object is the empty string. The corresponding row just keeps being empty, instead of showing my requested @"EMPTY". Any ideas?

  • SQLAlchemy automatically converts str to unicode on commit

    - by Victor Stanciu
    Hello, When inserting an object into a database with SQLAlchemy, all it's properties that correspond to String() columns are automatically transformed from <type 'str'> to <type 'unicode'>. Is there a way to prevent this behavior? Here is the code: from sqlalchemy import create_engine, Table, Column, Integer, String, MetaData from sqlalchemy.orm import mapper, sessionmaker engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() table = Table('projects', metadata, Column('id', Integer, primary_key=True), Column('name', String(50)) ) class Project(object): def __init__(self, name): self.name = name mapper(Project, table) metadata.create_all(engine) session = sessionmaker(bind=engine)() project = Project("Lorem ipsum") print(type(project.name)) session.add(project) session.commit() print(type(project.name)) And here is the output: <type 'str'> <type 'unicode'> I know I should probably just work with unicode, but this would involve digging through some third-party code and I don't have the Python skills for that yet :)

  • PHP PDO: Fetching data as objects - properties assigned BEFORE __construct is called. Is this correc

    - by Erik
    The full question should be "Is this correct or is it some bug I can't count on?" I've been working with PDO more and in particular playing with fetching data directly into objects. While doing so I discovered this: If I fetch data directly into an object like this: $STH = $DBH->prepare('SELECT first_name, address from people WHERE 1'); $obj = $STH->fetchAll(PDO::FETCH_CLASS, 'person'); and have an object like this: class person { public $first_name; public $address; function __construct() { $this->first_name = $this->first_name . " is the name"; } } It shows me that the properties are being assigned before the __construct is being called -- because the names all have " is the name" appended. Is this some bug (in which case I can't/won't count on it) or is this The Way It Should Be. Because it's really quite a nice thing the way it works currently.

  • Unexpected output from Bubblesort program with MSVC vs TCC

    - by Sujith S Pillai
    One of my friends sent this code to me, saying it doesn't work as expected: #include<stdio.h> void main() { int a [10] ={23, 100, 20, 30, 25, 45, 40, 55, 43, 42}; int sizeOfInput = sizeof(a)/sizeof(int); int b, outer, inner, c; printf("Size is : %d \n", sizeOfInput); printf("Values before bubble sort are : \n"); for ( b = 0; b &lt; sizeOfInput; b++) printf("%d\n", a[b]); printf("End of values before bubble sort... \n"); for ( outer = sizeOfInput; outer &gt; 0; outer-- ) { for ( inner = 0 ; inner &lt; outer ; inner++) { printf ( "Comparing positions: %d and %d\n",inner,inner+1); if ( a[inner] &gt; a[inner + 1] ) { int tmp = a[inner]; a[inner] = a [inner+1]; a[inner+1] = tmp; } } printf ( "Bubble sort total array size after inner loop is %d :\n",sizeOfInput); printf ( "Bubble sort sizeOfInput after inner loop is %d :\n",sizeOfInput); } printf ( "Bubble sort total array size at the end is %d :\n",sizeOfInput); for ( c = 0 ; c &lt; sizeOfInput; c++) printf("Element: %d\n", a[c]); } I am using Micosoft Visual Studio Command Line Tool for compiling this on a Windows XP machine. cl /EHsc bubblesort01.c My friend gets the correct output on a dinosaur machine (code is compiled using TCC there). My output is unexpected. The array mysteriously grows in size, in between. If you change the code so that the variable sizeOfInput is changed to sizeOfInputt, it gives the expected results! A search done at Microsoft Visual C++ Developer Center doesn't give any results for "sizeOfInput". I am not a C/C++ expert, and am curious to find out why this happens - any C/C++ experts who can "shed some light" on this? Unrelated note: I seriously thought of rewriting the whole code to use quicksort or merge sort before posting it here. But, after all, it is not Stooge sort... Edit: I know the code is not correct (it reads beyond the last element), but I am curious why the variable name makes a difference.

  • Action script 3 bitmap glitch, alpha fade in out

    - by user150946
    I have actually solved this problem but it was a weird one so I will post it and my solution. I had a movie clip with several children each of which had it's own alpha settings. It also had a bitmap child object with a masked movie clip sitting on top of it. I was fading in and out the parent movie clip and was getting some odd results all of the alpha settings of the children were being removed and the bitmap was glitching and showing the contents of the masked object that was above it. The problem was that my alpha value for fully opaque was 100 (as in AS2) not 1 (as per AS3). It took me ages to work this out so hopefully this helps someone else.

  • Can I add custom methods/attributes to built-in Python types?

    - by sfjedi
    For example—say I want to add a helloWorld() method to Python's dict type. Can I do this? JavaScript has a prototype object that behaves this way. Maybe it's bad design and I should subclass the dict object, but then it only works on the subclasses and I want it to work on any and all future dictionaries. Here's how it would go down in JavaScript: String.prototype.hello = function() { alert("Hello, " + this + "!"); } "Jed".hello() //alerts "Hello, Jed!" Here's a useful link with more examples— http://www.javascriptkit.com/javatutors/proto3.shtml
